RAID – redundant array of inexpensive/independent disks

What a tricky little thing it is, especially the non-Hardware variety (i.e. a dedicated RAID controller card via PCI bus or PCI-e bus).

These are some of the things I think I know about RAID in GNU:

  1. BIOS RAID (a.k.a. fakeRAID) is built onto motherboards to please Windows Users, because XP Home and XP Pro do not come with support for redundant arrays (RAID levels 1 and up). This means it only supports stripping (RAID 0). BIOS RAID is there to ‘save the day’ and support redundancy, as in RAID 1, 5, 1+0.
  2. In GNU, one needn’t turn on BIOS RAID, one only needs dmraid (or mdamd), and more than one hard drive (only one is required, but more are highly recommended). All RAID levels are supported via Linux software RAID. The kernel has had lots of modifications over the years to very easily support RAID 0, 1, 3, 4, 5, 1+0.
  3. dmraid (device-mapper raid) and mdadm (multiple-devices admin) are tools used to manage RAID arrays. I have not yet figured out the differences between them and which one I should use. openSUSE 10.3 has them both installed – adding lots of confusion.


I am quite excited that things are going well in the computer business department. After all, I’ve had three clients so far, all pleased with my work. For $30/hr it is very affordable. I’m only working about 2-4 hours. They get everything they want for between $60-$120.

God of War

I’m pretty stoked about my PS2. I’ve been playing lots of very good games lately – especially some of the great classics. I don’t regret now having played these games before. I did other amazing things before.

God of War was excellent. Lots of cool enemies, beautiful puzzles, cool landscapes, killer story line. Kratos is a bad ass, with pimpin’ chains.

Bully is pretty fun – albeit childish

Need For Speed: Carbon is very exciting. I’m trying to win all the pink slips.

Prince of persia. There’s an excellent adventure. More thinking than fighting – fighting always an important part. Solid adventure, solid storyline. Prince of persia sands of time is the game I aim to beat now.

All of these games are playing from my HD. A most excellent invention. Props to the teams from HD loader, WinHIIP, Console Exploits. Thanks to Sony for a killer system, and for all the software developers. If the games were only half the price, I might just buy them …


a very interesting thread. thank you to all. I have been able to see the point of view of GNU/Linux developers. Sometimes one forgets what ‘volunteerism’ really means, and the efforts that are expended and the sacrifises endured for the good of the ‘group’


Also, I do believe that gnu is very powerful on the desktop, and even the corporate desktop. When you get to specialised stuff, like Pat mentioned a very good video editing software, those gaps will be filled in with players like Adobe (which just joined the Linux Foundation some days ago). I do not know whether Adobe makes video editing software, but companies like it will be able to produce what is needed. The vision/spirit of GNU GPL and FLOSS will slowly wane as players like Microsoft release Public Licences approved as ‘free software’ by the OSI and FSF. They will dilute what it means to make libre software (not $0.00 software).

Oh and a side note – GNU was never about software without price. It was never what the ‘movement’ was about. Never. It was about making software that one could use in any way one felt, and modify in any way one felt. It was about people helping people. Yes, it could be seen as hobbyist, and is still seen in that way by many thousands of people. But a large proportion of FLOSS developers are making money writing the code (see more). Development of GNU tools for the server end of things (giant corporate servers) is highly funded, with billions invested annually. The ‘hobbyist’ point of view isn’t invalid, nor is it wrong. It can be perceived as helpful, beneficial, and supportive. Forums like these and other gnu/linux forums are full of newbies trying to get some help. And they do for the most part, because of the helpful community that runs things. Development is fast, secure, open, and admired by many in the professional software industries. Neat innovations come out daily, and it is one of the fastest growing ‘pockets’ in the Information Industry. ‘Open Source’ is so hip right now :roll:

Also, because software is developed by users for users (not in all cases i know) there is a trend that it is tailored to their needs, uses, and desires. Bugs are fixed quickly, and end-users can usually get into direct (Internet) contact with the makers of the software.

Relatively small projects (like pmagic) are not going to receive the sort of financial assistance required. Nor are they popular enough to warrant outside developers. Most people using it (i guess) are end-users, with little to no knowledge of programming. They will only be able to assist by praise (thank you) and providing [small] donations.

If Pat decides to end supporting pmagic many thousands will be upset. When he announced in Oct or Nov 2007 that pmagic would end, he received several hundreds of dollars in donations! A protest, if you will, so that he continue his development. He received more donations in that month, than [almost] all the previous months combined. That spurred him to go on – and he has. I think he enjoys it very much. That is where the ‘community’ aspect comes in.

Furthermore, Pat never had to re-write pieces of code such as compilers, booting programs, and other basic utilities to make his OS (pmagic). That stuff was already MADE! It was FLOSS and he could copy it, change it, use it, and redistribute it at no penalty to him or anybody! All developers are working on the same projects, indirectly. They work on the work of others, to contantly improve on the work done before. Never do they need to, as the saying goes, ‘re-invent the wheel.’

Yes — it sucks BIG BALLS when people rip off FLOSS. They download it, copy it to disc, sell it for $10-$100 and never give a cent back to developers. I hate that. I honestly think that the GNU GPL should not allow for commercial re-distribution unless that author/developer agrees in writing. No one should make money from someone else’s work and give nothing back.

But what the hell do I know – i’m just an end-user :lol:

who contributes to linux?

  • This is the largest distributed software development project in the world.
  • Since 2005, the number of active kernel developers has tripled, reflecting the rowing importance of Linux in the embedded systems, server, and desktop markets.
  • Between 70 and 95 percent of those developers are being paid for their work, dispelling the “hobbyist” myth present from the start of open source development.
  • “Never before in the history of computing have there been so many companies, users and developers united behind one project, specifically one that has seen so much commercial success,” said Jim Zemlin, executive director at The Linux Foundation
  • More than 70 percent of total contributions to the kernel come from developers working at a range of companies including IBM, Intel, The Linux Foundation, MIPS Technology, MontaVista, Movial, NetApp, Novell and Red Hat. These companies, and many others, find that by improving the kernel they have a competitive edge in their markets.

The top 4 Corporate Contributers are:
1) Red Hat, 11.2 percent
2) Novell, 8.9 percent
3) IBM, 8.3 percent
4) Intel, 4.1 percent
